Design Paper for the impact evaluation of the Root and Tuber Improvement & Marketing Program (RTIMP)
This document, jointly authored by the International Fund for Agricultural Development (IFAD) and Participatory Development Associates (PDA), lays out the design of the impact evaluation of the Root & Tuber Improvement and Marketing Program (RTIMP) in Ghana. Aiming at improving rural poor people’s livelihoods in Ghana through the development of commodity chains for Roots and Tubers (R&T) supplied by smallholders, the RTIMP consisted of three main areas of work: a) linking of smallholders to old and new markets; b) enhancing smallholder R&T production; and c) enhancing smallholder R&T processing.
The content of this design paper is as follows. The first section briefly describes the impact evaluation approach called PIALA. The second section presents the RTIMP Theory of Change (ToC). The third section continues with the Data Collection Matrix (DCM) laying out the assumptions, evaluation questions and methods. The fourth section presents the multi-stage sampling strategy. The fifth section provided an overview of the methods used to inquire the various populations at different levels. The sixth section outlines the approach taken for data collation, quality monitoring, contribution analysis and rating. Finally, the last section shows the timeline for the evaluation. A bibliography, list of references and annexes are added at the end. The annexes include the desk review note, the sampling frame and procedure, the field research schedule, the district data collation table, and finally, the approved budget.
The Paper was primarily sponsored by IFAD, the Bill and Melinda Gates Foundation and the Ministry of Food and Agriculture (Government of Ghana).
